This program prompts the user to enter the name of an item and then checks if the item exists in the list. If the item is found, it displays the item's details such as name, SKU number, unit cost, and quantity on hand.#### Code Explanation```javaimport java.util.LinkedList;import java.util.Scanner;public class MyLL{ public static void main(String[] args) { String newitem; LinkedList l = new LinkedList(); l.add(new Item("soap", "1234567890", 10.5)); l.add(new Item("bag", "0987654321", 20.8)); l.add(new Item("spoon", "9876565431", 22.8)); l.add(new Item("wallet", "1234654321", 25.6)); l.add(new Item("lighter", "99812344321", 28.10)); l.add(new Item("purse", "9977614321", 26.21)); l.add(new Item("book", "9876745321", 7.8)); l.add(new Item("pen", "0187254321", 17.12)); l.add(new Item("laptop", "938563321", 1000.7)); l.add(new Item("mobile", "0987168881", 500.9)); l.add(new Item("basket", "0982653341", 20.81)); l.add(new Item("television", "998794929", 1020.6)); System.out.println("Please enter the item that you want to search in the list"); Scanner sc = new Scanner(System.in); newitem = sc.next(); for(Item i : l) { if(i.item_name.equals(newitem)) { System.out.println("The item is present in the list, here are the details:"); System.out.println("Item name: " + i.item_name); System.out.println("SKU Number: " + i.SKU); System.out.println("Unit Cost: " + i.unit_cost); System.out.println("Quantity on hand: " + i.quantity_on_hand);

### Java Program to Search for an Item in a LinkedList

In this tutorial, we will explore a Java program that uses a `LinkedList` to store and search for items. This program prompts the user to enter the name of an item and then checks if the item exists in the list. If the item is found, it displays the item's details such as name, SKU number, unit cost, and quantity on hand.

#### Code Explanation

```java
import java.util.LinkedList;
import java.util.Scanner;

public class MyLL
{
public static void main(String[] args)
{
String newitem;

LinkedList<Item> l = new LinkedList<Item>();

l.add(new Item("soap", "1234567890", 10.5));
l.add(new Item("bag", "0987654321", 20.8));
l.add(new Item("spoon", "9876565431", 22.8));
l.add(new Item("wallet", "1234654321", 25.6));
l.add(new Item("lighter", "99812344321", 28.10));
l.add(new Item("purse", "9977614321", 26.21));
l.add(new Item("book", "9876745321", 7.8));
l.add(new Item("pen", "0187254321", 17.12));
l.add(new Item("laptop", "938563321", 1000.7));
l.add(new Item("mobile", "0987168881", 500.9));
l.add(new Item("basket", "0982653341", 20.81));
l.add(new Item("television", "998794929", 1020.6));

System.out.println("Please enter the item that you want to search in the list");
Scanner sc = new Scanner(System.in);
newitem = sc.next();

for(Item i : l)
{
if(i.item_name.equals(newitem))
{
System.out.println("The item is present in the list, here are the details:");
System.out.println("Item name: " + i.item_name);
System.out.println("SKU Number: " + i.SKU);
System.out.println("Unit Cost: " + i.unit_cost);

You may have found it somewhat tedious and unpleasant to use the debugger and visualizer to verify the correctness of your addFirst and addLast methods. There is also the problem that such manual verification becomes stale as soon as you change your code. Imagine that you made some minor but uncertain change to addLast]. To verify that you didn't break anything you'd have to go back and do that whole process again. Yuck. What we really want are some automated tests. But unfortunately there's no easy way to verify correctness of addFirst and addLast] if those are the only two methods we've implemented. That is, there's currently no way to iterate over our list and get bad its values and see that they are correct. That's where the toList method comes in. When called, this method returns a List representation of the Deque. For example, if the Deque has had addLast (5) addLast (9) addLast (10), then addFirst (3) called on it, then the result of toList() should be a List with 3 at the…
